+Given a site configuration that contains this menu entry:
+
+{{< code-toggle file=hugo >}}
+[[menus.main]]
+  name = "IRC"
+  url = "irc://irc.freenode.net/#golang"
+{{< /code-toggle >}}
+
+Attempting to use the `url` value directly in an attribute:
+
+```go-html-template
+{{ range site.Menus.main }}
+  <a href="{{ .URL }}">{{ .Name }}</a>
+{{ end }}
+```
+
+Will produce:
+
+```html
+<a href="#ZgotmplZ">IRC</a>
+```
+
+`ZgotmplZ` is a special value, inserted by Go's [template/html] package, that indicates that unsafe content reached a CSS or URL context.
+
+To indicate that the HTML attribute is safe:
+
+```go-html-template
+{{ range site.Menus.main }}
+  <a {{ printf "href=%q" .URL | safeHTMLAttr }}>{{ .Name }}</a>
+{{ end }}
+```
+
+{{% note %}}
+As demonstrated above, you must pass the HTML attribute name _and_ value through the function. Applying `safeHTMLAttr` to the attribute value has no effect.
